Dong Van has long become an extremely attractive and famous tourist destination for domestic and foreign tourists when it possesses many beautiful scenes and especially the Lung Cu flagpole, a symbol very sacred of the country of Vietnam. But that is not all of Dong Van. Hidden deep in the cat's ear rock layer is a small town named Pho Bang. This place is a little-known land, although it has been forgotten by years, it still retains its wild, ancient and unusually peaceful features.
